A deep-sea coral's secret weapon against hungry predators—sweeper tentacles.
A bamboo coral’s stony branches contain thousands of tiny polyps living and working together. The individual polyps stretch feathery tentacles into the currents to grasp plankton and other particles of food drifting in the currents.
When predators like nudibranchs and sea stars try to make a meal of a coral’s polyps, the colony can put up a fight. These fleshy sweeper tentacles are loaded with powerful stinging cells that gently sway along the base of this shaggy bamboo coral (Isidella tentaculum) to keep predators from crawling up to eat those precious polyps.

How? The Squid Facts Project. It's a street art campaign and hotline that texts folks squid facts!
Only snag in this hair-brained plan is that texting people is kiiinda expensive. So! I teamed up with Philly artist Corey Danks to sell shirts to keep the hotline running. Every one of those shirt dollars helps deliver squid facts to people.
Like, over 70,000 people over the last year!!! Isn't that wild?
So anyway. Get a shirt. They're cool, *and* they keep people learning about squid. It's a beautiful thing.
Also, the backs have the squid facts hotline on them so by wearing these you're helping people learn about squid too.
If you can't buy one, give us a reblog. I run a small science education nonprofit called Skype a Scientist, we're scrappy but trying so hard!!
The dumbo octopus (Grimpoteuthis) is a deep sea animal that lives on the ocean floor at extreme depths of 9,800 to 13,000 feet.
Females usually find a mate around their second birthday and take a seamen packet from the male so they can fertilize their eggs on the go when they please. They can even get pregnant while being pregnant, they’re basically always pregnant.
